"The FreeBSD 7.1 release comes as FreeBSD developers push toward
a FreeBSD version 8.0 later this year. The FreeBSD 7.1 release also
demonstrates how the open source ecosystem can extend across
company lines as well different operating systems. FreeBSD is one
of the earliest open source operating system projects and is a
direct descendant of the original open source BSD work performed at
the University of California, Berkeley. "DTrace is a mature and
compelling technology for performance monitoring developed
originally by Sun, released as open source as part of OpenSolaris,"
FreeBSD core team member Robert Watson told InternetNews.com.
"While we have had many tools for specific sorts of analysis in the
past, DTrace is an excellent general-purpose framework for managing
and presenting trace data, and also allowing us to more easily add
new types of tracing."
